Novel approach to preparation of LiMn2O4 core/LiNixMn2-xO4 shell composite

Abstract. Combining two methods, coating and doping, tomodify spinel LiMn2O4, is a novel approach we used to synthesize active material. First we coated the LiMn2O4 particles with the nickel oxide particles by means of homogenous precipitation, and then the nickel oxide-coated LiMn2O4 was calcined at 750 8C to form a LiNixMn2-xO4 shell on the surface of spinel LiMn2O4 particles.
